Systems and methods for demotion of content items in a feed

1. A computer-implemented method comprising:

determining, by a computing system, a value associated with at least one signal indicative of objectionable material in a content item published in a social networking system, wherein the at least one signal indicative of objectionable material in a content item is based on information in one or more comments published in response to the content item and includes a domain signal relating to a number of links provided by users in comments posted in response to content items published by a domain that published the content item, wherein the links direct to websites that publish content to identify false information as false;

comparing, by the computing system, the value associated with the at least one signal indicative of objectionable material with a threshold value associated with the at least one signal;

determining, by the computing system, a demotion value in response to satisfaction of the threshold value associated with the at least one signal; and

adjusting, by the computing system, a rank value associated with presentation of the content item in a news feed based on the demotion value.

2. The computer-implemented method of claim 1 , wherein the at least one signal includes a keyword signal relating to a number of responses, including one or more keywords indicative of objectionable material, to a content item.

3. The computer-implemented method of claim 1 , wherein the at least one signal includes a reporting signal relating to a number of users who have reported an objection to the content item.

4. The computer-implemented method of claim 1 , wherein the adjusting a rank value comprises:

lowering the rank value.

5. The computer-implemented method of claim 1 , wherein the determining a demotion value comprises:

assigning the demotion value in proportion to the value associated with the at least one signal indicative of objectionable material.

6. The computer-implemented method of claim 1 , further comprising:

discounting the demotion value for a user when the content item is associated with a domain to which the user is subscribed.

7. The computer-implemented method of claim 1 , further comprising:

discounting the demotion value when the content item contains one or more keywords that are indicative of objectionable material.

8. The computer-implemented method of claim 1 , wherein the computing system is controlled by the social networking system.

9. A system comprising:

at least one processor; and

a memory storing instructions that, when executed by the at least one processor, cause the system to perform:

determining a value associated with at least one signal indicative of objectionable material in a content item published in a social networking system, wherein the at least one signal indicative of objectionable material in a content item is based on information in one or more comments published in response to the content item and includes a domain signal relating to a number of links provided by users in comments posted in response to content items published by a domain that published the content item, wherein the links direct to websites that publish content to identify false information as false;

comparing the value associated with the at least one signal indicative of objectionable material with a threshold value associated with the at least one signal;

determining a demotion value in response to satisfaction of the threshold value associated with the at least one signal; and

adjusting a rank value associated with presentation of the content item in a news feed based on the demotion value.

10. The system method of claim 9 , wherein the at least one signal includes a keyword signal relating to a number of responses, including one or more keywords indicative of objectionable material, to a content item.

11. The system method of claim 10 , wherein the at least one signal includes a reporting signal relating to a number of users who have reported an objection to the content item.

12. A non-transitory computer-readable storage medium including instructions that, when executed by at least one processor of a computing system, cause the computing system to perform a method comprising:

determining a value associated with at least one signal indicative of objectionable material in a content item published in a social networking system, wherein the at least one signal indicative of objectionable material in a content item is based on information in one or more comments published in response to the content item and includes a domain signal relating to a number of links provided by users in comments posted in response to content items published by a domain that published the content item, wherein the links direct to websites that publish content to identify false information as false;

comparing the value associated with the at least one signal indicative of objectionable material with a threshold value associated with the at least one signal;

determining a demotion value in response to satisfaction of the threshold value associated with the at least one signal; and

adjusting a rank value associated with presentation of the content item in a news feed based on the demotion value.

13. The non-transitory computer-readable storage medium of claim 12 , wherein the at least one signal includes a keyword signal relating to a number of responses, including one or more keywords indicative of objectionable material, to a content item.

14. The non-transitory computer-readable storage medium of claim 13 , wherein the at least one signal includes a reporting signal relating to a number of users who have reported an objection to the content item.
